To all whom it niay concern? Be it known'that I, WHZLIAM E. GERTH,

a citizen of-t-he United States, residing at 'useful Improvements in Non-Skiddin Chicago, in the county of Cook and State of Illinois, have invented certain new 861:.

vices for Wheels, of which the following is a s ccification. it

y invention relates to means for pre venting the wheels of vehicles from sli ping or-skidding; and the invention has. or its 'object to provide non-skidding meansof novel character suitable particularly for. the.

. wet'or inudd pneuniatic tires of motor driven vehicles,

which can be readily attached to and detached from the wheetas occasion demands,

which can be cheaply manufactured, and

which will taken firm grip on the pavement so as to. etfeetuall prevent the slipp ng or skidding of the -w icel when the pavement is A further important-"object of the invention is to provide a non-skidding-devlce having a certain capacity for adjustment so that,

it can be made .to'accuratcly fit tires which may be somcwh'at difl'ercnt in size-0r inflated to a greater or lessdegree. A further objectof, he invention is to movide a. device-of this character which can he attached to the wheel and removed therefrom by a very few mani ulations requirg but little time and wit lout dcm'ouhtlng the wheel."

A further object is-to provide non-skidding means consisting of a number of separatedeviccs which are separately arranged on the wheel so that'a greater or less number may be used according to the size of the wear out as do most of the'non-skidding de-- particular wheel or the amount of. the peripheral surface of its tirc which, under any particular circumstances, 1t is found necessary to cover. a

A further object of the invention, is, to provide n n-skidding. dev'roes which will protect the tires (in-which they are used instead of injuringthem and causing them to vices heretofore hscd. I a

The invention ,is illustrat d, in certain preferred embodiments, in the accompanyin drawings whcrcinl igurcl is ajvicwin elevation of a part ofa vehicle wheel showing the tire providod with-one form of noms'kiddihg device mnstructcd in accordance with my inven-' invention-consistent af numberof metal elements whichfitriroundtheEtire' and are detachably securedtb' 1the wheel=, for example,

to the spokes. "I-l ief"device shown in Figs.

-1, 2 and 3 consists of a" rigid curved metalplate 28 to which are riveted the preferably tool steel studs '29.? 'Th'e plate 28 is provided' with four curved. arms 30 which are preferably of somfleitible material such 'as s ring steel. Bylmzrking the non-skidding evice,.or portions' ofiit, flexible the device has'the capacity tofit tires. which are some- .what different-in size/and shape or which are not uniformly inflated. To the ends of the arms 30 are secured chains 31 which may be covered, if desired, with any suitable ma- The non-skiddingfxhleans' provided by my teria'l. When. the non-skidding devices are in place onthe tire the chains are engaged with anchoring devicesrwhich'are fixed 'to the wheel, for example, to, the spokes. Preferabl these anchoring devices are not removed rom the wheel when the non-skidding devices 'are removed. I have shown one of the 'anchoringdevices in detail in Figs. 4 and 5. It consistsof two clamping members 32. and 33 which embrace the spoke and are secured togetber'by the bolts 34. The latter may be formed with rings or eye lets 35 to receive-the-hooks 36 on the chains- 31 atone end of the non-skidding device. The clamping members 32 and '33 are formed at each endfiivith lugs 37, 38-c1otted toreceive the shank 39' of the thumb screw 40. Thelatterhas'an internalthread which tobringthe lug-'43 under lug 38 the thumb By turningthe'thumbscrew so as screw is hcldin place.

It. will be understood that the anchoring y ble strips of metal extending diagonally devices, as they have been termed, are ordi narily not removed from the wheel after they have been once put'in place.

\Vhen the non-skidding devices are to ,be used they are slipped over the tire and the hooks 36 engaged with the eyelets 35 on oneof the anchoring devices and the chains at, the other end of the non skidding device engagedlwith the hooks 41 of the next adjacent anchoring device. By turning the thumbscrews' 40 the non-skiddin devices may be tightly-{bound to the whee,

The u'mber of devices used on the wheel may be ayaried according to-thex size of the wheel as, the need of covering or' protecting more or' less of the tire.

Therefoie I dojnot limit myself to the particulars describedlgind claimed except so far as they are made specifically limitationson certain of the claims herein.

I claim:
